ABSTRACT

Objective: This study was undertaken to determine the positive rate for computed tomography pulmonary angiograms (CTPAs) at the University Hospital of the West Indies (UHWI), to compare the positive rate at the UHWI to that reported in the literature and to compare the rates of positive CTPAs between the genders.

Method: Data were obtained from the databases of the Radiology Department of the UHWI. All CTPAs performed to confirm a c linical d iagnosis o f p ulmonary embolism a nd t he results issued during the period January 1st 2013 and December 31st 2013 inclusive were reviewed. Only initial examinations of adequate diagnostic quality were included in the study.

Results: Three hundred and thirteenth CTPAs were performed for initial diagnosis of pulmonary embolism. Sixteen examinations were excluded for inadequate diagnostic quality. Two hundred and ninety-seven examinations on 223 females and 74 males were included in the study. The means for age were 49.7 years and 55.1 years, respectively; the difference in the means was significant (p < 0.0 5). Ninety-four examinations (31.6%) on 22 males (7.4%, mean age 58.4 years) and 72 females (24.2%, mean age 57.5 years) were positive for pulmonary embolism. The difference in the means was not significant (p = 0.8). On Chi-squared test there was no significant difference in the percentage of positive CTPAs between males and females (p = 0.7).

Conclusions: The percentage of positive CTPAs at the UHWI is high. There was no significant difference between the genders in the percentage of positive CTPAs or the mean age at which pulmonary emboli were detected.
